To get back on topic the 37-640 was a mid level from the 1937 production yr. It sports a tuned rf amp stage (for better sensitivity), Push/pull 6F6's in the audio output stage (higher output and less distortion than sets w/a single 6F6 or 42 tube), shadowmeter tuning, coverage from the BC band to 22mc or so. A step up from the 610-630 chassised sets.
THe negatives are it's a 1937 model set. Philco in '37 and 38 used a design that has a chassis mounted in the main chassis to contain the rf parts like the band switch, rf and mixer coils and such. This makes these a bit more difficult to service because some of the components are difficult to get to and replace with out removing this sub chassis. THe shadowmeter on all Philc set is suspect. It uses a lot of very fine magnet wire and it can go bad from old age. You can repair them but is a bit of a job. Other than these things generally service is pretty average and is a good playing and sounding sets to enjoy the BC station and lots of good coverage on the SW bands to hear far away places with strange sounding names.
This one has the MX cabinet (Modern Console). Something Philco started about 1933 or so. The MX's are the console and the MB's are the table set. I like the different design.
I know I have too much time on my hand but it beats cleaning the house.

figure out what all those squiggly meant.
